Technically speaking Necas is outscoring Rantanen on the season by 2 in 1 extra gameI more referring to the other poster saying Necas is outproducing Rantanen for the Avs, which is false. The trade has more nuances than just points being put up (cap, future contract/years, ability for Avs to acquire other players at TDL), but in terms of the 1 for 1 trade, they downgraded in production.
Also, I think the Avs made out great and each time I watch Necas with the Avs, he reminds me of a Mackinnon-lite.
